Abstract. In the paper is verified the existence of statistical
relationships between higher-order velocity moments in the plain wake behind
a cylinder. Although some differences are present, these connections are
analogue to the general trends previously noticed in turbulent boundary
layer and free jet: SSU,V=10*SU,V, SFU,V=15*FU,V-30,
FU=1.62*SU2+2.65 and FV=3.13*SV2+3.48.
They represent a good base for further statistical analysis of turbulent
flows and resolving the closure problem.
